AI Technical Summary

Benefits of technology

The invention is a protective garment that can shield or block radiation, such as X-rays, with high efficiency. It is resistant to abrasion, flexibility, and environmental stress cracking, even after exposure to isopropyl alcohol. The garment is designed to be used for more than two years without any significant damage to its ability to block radiation.

Problems solved by technology

Ionizing radiation is widely used in industry, medicine and laboratory, and it presents a significant health hazard.

Embodiment Construction

[0028]This description of the exemplary embodiments is intended to be read in connection with the accompanying drawings, which are to be considered part of the entire written description. In the description, relative terms such as “lower,”“upper,”“horizontal,”“vertical,”, “above,”“below,”“up,”“down,”“top” and “bottom” as well as derivative thereof (e.g., “horizontally,”“downwardly,”“upwardly,” etc.) should be construed to refer to the orientation as then described or as shown in the drawing under discussion. These relative terms are for convenience of description and do not require that the apparatus be constructed or operated in a particular orientation. Terms concerning attachments, coupling and the like, such as “connected” refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both movable or rigid attachments or relationships, unless expressly described otherwise.

Abstract

A filled composition for radiation shielding includes at least one polymer ingredient and at least one metal-containing filler. The at least one polymer ingredient is selected from the group consisting of a polyolefin elastomer, a polyolefin co-polymer, a polyolefin ter-polymer, and a combination thereof. The polyolefin elastomer, the polyolefin co-polymer, or the polyolefin ter-polymer includes monomer units derived from ethylene and at least one vinyl monomer having more than three carbon atoms. The at least one metal-containing filler is selected from a metal filler, a metal compound or a combination thereof.

Description

RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 720,553, filed Oct. 31, 2012, which application is expressly incorporated by reference herein in its entirety.FIELD[0002]The present disclosure relates to polymer composition and protective garments. More particularly, the disclosed subject relates to filled polymer compositions, resulting protective garments for radiation protection, and methods of making the same.BACKGROUND[0003]Protective garments and related equipment are designed to protect a user's body from harm or injury caused by hazards such as radiation. Ionizing radiation is widely used in industry, medicine and laboratory, and it presents a significant health hazard. Radiation blocking garments can shield a user's body and block radiation. For example, X-ray blocking garments are worn by people exposed to non-enclosed (open) X-ray beams having energies between 60 and 120 kV. In addition to efficiency in blocking radiatio...
